It used to show __start_notes as the backtrace. This one is with the head of Linus' tree as of a few minutes ago. So I did a git bisect, and the problem goes back to June 11. The Warp boots and seems to run fine. So I didn't notice until looking at the logs for a different problem. I have since added a test to my regression tests to look for badness or oops in the logs. The git bisect returned: 871fa90791a6f83dd8e2e489feb9534a8c02088d is first bad commit That is it, no more info.... strange. git show 8714...088d gives: Merge: 7702667... 79f52b7... Author: Linus Torvalds Date: Thu Jun 11 11:27:09 2009 -0700 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/shaggy/jfs-2.6 * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/shaggy/jfs-2.6: jfs: Add missing mutex_unlock call to error path missing unlock in jfs_quota_write() The Warp has jfs disabled, so I don't know why it would affect us, especially this realy in the boot! Anyway, I tried to revert the patch: $ git revert 871fa90791a6f83dd8e2e489feb9534a8c02088d fatal: Commit 871fa90791a6f83dd8e2e489feb9534a8c02088d is a merge but no -m option was given. So, anybody got an idea what is going on here? Or how I can revert the patch. I am not a git expert, so if I am doing this wrong, let me know.
